Neurology: The era of vascular therapy is coming, and patients with posterior circulation ischemia may usher in new opportunities!

Acute ischemic stroke, intracranial arterial vascular ischemic necrosis of the brain tissue of local stenosis or occlusion due to ischemia, hypoxia caused by high morbidity and mortality, especially after ischemic stroke cycle disease The disability rate and the mortality rate are as high as 80%, which seriously affects the quality of life of patients , and increases the medical and economic burdens of the family and society

The disability rate and fatality rate of stroke blood vessels, especially posterior circulation ischemic stroke, is as high as 80%, which seriously affects the quality of life of patients , and increases the medical and economic burdens of families and society

In particular, the disability rate and fatality rate of posterior circulation ischemic stroke are as high as 80%, which seriously affects the quality of life of patients , and increases the medical and economic burdens of the family and society

At present, intravenous thrombolysis is the most effective ultra-early treatment method for acute ischemic stroke patients whose onset time is less than 6 hours

Recently, experts from the Department of Radiology and Neurology at the University of Texas Southwestern Medical Center reviewed the clinical, imaging and anatomical features of posterior circulation ischemia (PCI), and dealt with basilar artery occlusion (BAO) Perform a systematic review of related results
.

The results were published in the journal Neurology

Researchers review the literature to identify publications describing the risk factors, etiology, clinical manifestations, and imaging of PCI
.

Perform a systematic review based on the "Preferred Reporting Project for System Review and Meta-Analysis"

The results show that PCI accounts for 15%-20% of strokes
.

In general, the risk factors are similar to anterior circulation stroke

Dizziness (47%), unilateral limb weakness (41%), and dysarthria (31%) are the most common symptoms

Recent trials have shown that endovascular treatment can make the recanalization rate of BAO reach more than 80%
.

Among the selected patients, 30%-60% of patients receiving endovascular treatment can obtain good curative effects, while patients who do not receive endovascular treatment

Recent trials have shown that endovascular treatment can make the recanalization rate of BAO reach more than 80%

It can be seen that PCI can manifest as fluctuating symptoms or clinical findings, which overlap with stroke-like cases and anterior circulation ischemia, making the diagnosis more dependent on imaging
